CABLE-PUMP.

Specification of Letters Patent.

sppiication'iiied August 1s,19i9. ser-iai No. 318,401.v

To all whom t may concern.' y

Be it known that I, GEORGE GARTLING, a' citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Cable-Pump, of which the following is a specification.

This invention relates to appliances for lifting water through a casing by means of upwardly moving buckets that are attached to a cable; and the invention may be said to'consist in the provision of the novel features and in the improvedl construction, combination and arrangement of parts as herein shown, described and claimed.

rl`his cable pump is similar in construction and operation to the-chain pump described in my application for Letters-Patent, filed June 30, 1919, Serial No. 307,795; this appliance being an improvement of my former invention. n v

The .principal object of this invention is to provide a pump of the character described with buckets that are detachably connected to an endless cable; and means by which the buckets can be removed from the cable while it isunder tension.

-Another object of this invention is to pro vide a pump with a pump casing that has a larger internal diameter than the buckets on the endless cable; and which casinghas at the bottom end thereof a cylinder that has an internal diameter substantially the .same as the external diameter of the buckets.

Another object of this invention is to provide a cable pump that can be operated with small frictional resistance, and that can be cheaply constructed, easily assembled and repaired and which also will be exceptionally strong and durable and effective in faction.

A feature of the invention is shown in the mounting and operation of the endless cable and associated parts.

Another novel -feature of invention is shown in the mounting of the driving shaft and means for moving it to increase or de crease they tension on the pump cable.

Other objects, advantages yand features of invention may appear from the accompanyiiig drawings, the .subjoined detailed description and the appended claims.

The drawings illustrate the invention.

Fig. 5 is a section on the line m5 of Fig. 4l showing the means for attaching the buckets to the cable.

Fig. 6 is a section on the line w of Fig. 5, parts broken away.

Fig. 7 is a section on the line m7 The pump 1 has its upper end with the stand 2 that has its base by the anchor'bolts 4 to the pump platform 5 that is preferably formed of cement.

The platform 5 has the opening 6 through which the well casing 7 extends downward to the bottom of the well 8. f f

AThe stand 2 has the upwardly extending r flanges 9 to which are secured by the bolts 10the lugs 11 on pipe 12. The'lugs 11 are integral with the top of pipe 12, and by means of theirconnectionto the stand just described the pipe is suspended in the well 8 so that the lower end is near the bottom of the vwell. v At the lower end of the pipe 12 there is detachably connected a suction barrell that is preferably made of case hardened steel or tempered to resist thecutting effects of sand; and the interior diameter of thisbarrel is considerable less than the inside diameter of the pipe 12. Also this suction barrel is slightly longer than the distance between any two of the buckets 14 of the endless cable 15 so that there will always be one or ymore of these buckets in the barrel 13 when the pump is in operation.

The endless cable 15 is mounted on the pulley 16 that is secured by the key 17 to the driving shaft 18. This driving shaft of Fig. provided 3 secured Patented Aug. 30, 1921. v

ico

is mounted in the bearing boxes 19 that are. secured by the bolts 20 to upright anges 21 of the stand 2; and the shaft 18 is rotated by the pulley 22 which is driven from some source' of power not shown.

The pulley 16 has the spaced recesses 23 that fit the periphery of the rounded buckets 14 so that the cable 15 contacts with and lies snugly in the groove of the pulley 16.

Mounted in the vertical walls 24 of the stand 2 is a shaft 25 on which there is mounted the idle pulley 26 that is of smaller diameter than the pulley 16; and the purpose of this pulley is to direct the cable 15 forwardly and into the well casing after it has passed over the pulley 16, The pulley 26 is provided with the flanges 27 that are adapted to receive the rounded buckets 14 so that the cable 15 will contact with the periphery of the pulley.

The bottom end of suction barrel 13 is threaded to fit the socket 2S that is threaded into the reduced pipe end 29 of the shoe 30.y The pipe end 29 is integral with the upper end of the shoe 30, and the lower part of the inner wall of the pipe 29 has the beveled surfaces 31 that form a guide for the buckets 14 so that they will enter centrally the suction barrel 13.

Within the shoe 30 is the pulley 32 that is adapted to carry the cable 15, and ythis pulleyv is secured on the shaft 33 mounted in the bearing blocks 34. The pulley 32 is provided with the flanges that are adapted to receive the rounded buckets 14 so that the cable 15 can contact with the periphery of this pulley. p

Another pulley 36 on the shaft 36 is mounted between the bearing blocks 37 and 38 respectively7 that are `secured in the eX- tensions 37 and 38 on interior wall of shoe 30, and the purpose of this pulley is to prevent the escapement of the cable from the pulley 32 when the cable is slackened for repairor replacement of the buckets.

The upperI end of the shoe 30 has the opening 39 through which the cable and buckets descend when therpump is in operation. The lower end of the shoe 30 is contracted into the form of an inverted cone in which there are a plurality of small openings 40 for the passage of water from the bottom of the well into the cylinder. These small openings however prevent largeur-ook from entering the shoe 30 and obstructing the operation of the pump. Preferably the diameter of the cylindrical wall of shoe 30 is such that it4 can freely enter the well casing 7 and will fit so snugly that large rock or gravel cannot enter between the exterior surface of the cylinder' 30 and inner wall of the casing 7.

The buckets 14 are formed of the halves 41 and 42 which parts have between them the central opening 43 for the cable 15; and

also each of these halves 41 and 42 is provided with the sockets 44 that are adapted to fit snugly over the ends of the pin v45 when the halves of the bucket are secured together. The purpose of the pin 45 is to prevent longitudinal movement of the buckets on the cable 15; and this is accomplished by separating the strands of the cable 15 and inserting the pin therein. Then the halves 41 and 42 are placed together so that pins 45 have their ends in the sockets 44; after which the halves are secured together by the countersunk screws 46.

The opening 43 'from about'one-fourthV the distance from the center of buckets 14 is enlarged toward the outer surface of the buckets for the purpose of givingl play to the cable at its points of egress from the buckets so that' it can bend freely to the curvature of the pulleys when passing over them.

After the cable 15 is placed over the pulleys 16, 26 and 32, the right tension is applied to it by means of the rods 47 which rods have one end secured in the bosses 48 on the bearing blocks 19. The other ends of the rods 47 are threaded and pass through the openings 49 in the forwardly extending ledge 50 of the stand 2, and by means of the nuts 57 the bearing blocks 19 and associated parts can bel moved upwardly to apply tension to the cable.

This upward movement of the bearing blocks 19 is accomplished only when the bolts 20 are loosened for that purpose; after which the bolts 29 can move freely in the slots 52 in the stand 2; and when the right tension is applied to the cable 15 the bolts 2O are tight* erlied to hold the bearing blocks securely in p ace.

Also by loosening the bolts 2O and unscrewing the nuts 51 on the rods 47 the wheel 16 and associated parts can be lowered for the purpose of replacement or repair of parts.

or replacing the buckets 14 as with the foregoing improvement in the bucket construction they can be placed on the cable VWhile it is under full working tension.

1f desired the upper end of the pump casing 12 can be provided with a downwardly inclined discharge spout 53 that can be integrally connected to pipe 12.

1n practice the pump is assembled as here# 120 tofore described and placed in pumping position in a well. Then power is applied to the pulley 22 to rotate the pulley 16 in the direction of the arrows shown in Fig. 1, whereby the cable 15 will be moved so that as one line 125 of buckets move downward into the well 8 the other line of buckets will pass upward through the suction barrel 13 and pipe 12 and lift the water from the bottom of the well and discharge it from the spout 53.

n 1t is not necessary however to have slack 110 rin the cable 15 for the 'purpose of repairing The buckets 14 are positioned on the cable 15 so that their largest diameters are sub-A stantially the diameter of and contact with the inner wall of suction barrel 13. And when these buckets are drawn upward through this barrel 13 they lift the water above them and below them.

As previously stated the buckets 14 contact only with the wall of the barrel 13 and never touch the wall of pipe 12 so that there is frictional contact only with suction barrel 13.
